(CNN) -- South Africa's Caster Semenya has been given the all-clear to compete again as a woman after undergoing a series of gender tests, the International Association of Athletics Federation (IAAF) announced Tuesday.

"The process initiated in 2009 in the case of Caster Semenya has now been completed," the IAAF said in a statement on its website.

"The IAAF accepts the conclusion of a panel of medical experts that she can compete with immediate effect."

The IAAF added: "The medical details of the case remain confidential and the IAAF will make no further comment on the matter."

The 19-year-old Semenya was delighted to be able to return, after nearly a year of controversy and uncertainty.

"I am thrilled to enter the global athletics arena once again and look forward to competing with all the disputes behind me," she said in a statement released by her legal team.

Semenya emerged from obscurity at the beginning of last year to run world class times over 800 meters, culminating in victory over the distance in the world championships in Berlin in August.
